I just got my route 66 warranty in Jan and last week used it for new injectors. Started up my car in the morning and got violent shaking and white smoke. The injectors in bank two were bad however due to the new part nr which does not allow for mixing with old i was authorized to replace all 6. Glad that i got route 66 as they covered all expenses to include towing and a rental.
Also the indy shop i use in el paso is Moroni's BMW and they do amazing work and are very friendly. Moroni himself will let you go in the back as he runs diagnostics and explains all the faults and he is bmw master technician certified!
